The Evaluation of Methods for Determining the Concentration of Carbon Monoxide,
Abstract
The report presents analytical methods available for ground level use by trained technicians for determining low (25 ppm.) and aeronautically significant (up to 350 ppm.) concentrations of carbon monoxide (CO) in air. Five methods are discussed: The iodine pentoxide train yielded the most reliable and reproducible results of all the methods tested; however, its use is necessarily limited to research laboratories. The Bureau of Mines method may be considered to be the ideal method for routine laboratory use. The Beckman-McCullough method may be considered to be the ideal method for use by aircraft manufacturers or naval activities. The National Bureau of Standards method is self-contained, requires a minimum of equipment and little training for making the analyses; however, it was not sufficiently accurate for aircraft acceptance tests. Finally, the Wright Field modification of the National Bureau of Standards Method is discussed which differs from the parent method in that the time to develop a given color is measured instead of the color developed in a given time.
